Re: MSVC++ 6.0

     If you use the extern keyword, the linker searches (or is it the 
compiler???) throughout the program, not just the source file.  If you 
wanted to include it, you could, but you could make it more modular with the 
extern keyword, i.e.  you don't have to worry about EVERYTHING in the 
included file, only that one function you said was external.  Does this make 
sense, or not?
